Advanced Python for Data Science Assignment 10

1. Write an MPI program in which the processes with even rank print “Hello” and the processes with odd rank print “Goodbye”. Print the rank along with the message (for example “Goodbye from process 3”). Hint: remember that although the number of processes is fixed when the program starts, the exact number is not known until the Get_size() method is called.

   Make sure you have adequate comments and documentation in the code, and you follow good software engineering practices.

   Call the program mpi_assignment_1.py and commit it to the same repository you used for Assignment 3.

2. Write an MPI program that does the following for some arbitrary number of processes:

   1. Process 0 reads a value from the user and verifies that it is an integer less than 100.
   2. Process 0 sends the value to process 1 which multiplies it by its rank.
   3. Process 1 sends the new value to process 2 which multiplies it by its rank.
   4. This continues for each process, such that process i sends the value to process i+1 which multiplies it by i+1.
   5. The last process sends the value back to process 0, which prints the result.

   You can use either blocking or non-blocking operations. Any input read from the user must be validated correctly and exceptions handled. Make sure you have adequate comments and documentation in the code, and you follow good software engineering practices.

   Call the program mpi_assignment_2.py and commit it to the same repository you used for Assignment 3.
